Method for performing a vascular anastomosis

摘要

A method for performing a coronary artery bypass graft procedure on a patient to connect a bypass vessel to a target vessel includes the steps of creating an opening in the patient that communicates with the thoracic cavity of the patient; providing a bypass vessel having a lumen and at least one free end; passing the free end of the bypass vessel from the thoracic cavity through the opening to a position outside the body of the patient; attaching a connector to the free end of bypass vessel while the free end of the bypass vessel is outside the body of the patient; passing the free end of the bypass vessel from the position outside the body of the patient through the opening and into the thoracic cavity; and connecting the free end of the bypass vessel to a target vessel with the connector.

1. A method for joining at least two vascular vessels, comprising the steps of:
mounting on an applicator, an expandable cartridge having a distal portion containing recesses that hold joining elements and a proximal portion including pushing mechanisms; inserting at least a portion of the applicator inside at least one of said vessels; expanding the expandable cartridge to provide an expanded cartridge and move said joining elements from a first position to a second position wherein a distance between said joining elements is larger in said second position than in said first position; and discharging said joining elements from the expanded cartridge using said pushing mechanisms of said proximal portion of said expandable cartridge.
